We have installed the xpack in our elasticsearch, logstash and kibana as a trial. Then after that, we register a basic license. Everything works fine. We can monitor our elasticsearch nodes, kibana and logstash.
But for some reason, we uninstall the xpack bcoz we're fixing something, and we found out that its not about the xpack so we tried to reinstall it again, using the same .zip file just like before. Note that we already have the basic license and was already registered. Now, when we try to reinstall the xpack again in logstash, it throws us an error just like below;
why do we encounter this error? Nver mind.
